ELECTRIC POCKET-LAMP.

Specification of Letters Patent.

Patented 0611:. 1l, 1918..

Application led November 10, 1915. Serial No. 60,714.

rangement, by which the light of the lamp' can be shaded 0r directeddownward, so that it can be used to light the way or a map or the like,at the same time preventing the owner from being discovered.

For this purpose a shade is used, which can be brought in front of thelamp, so that the light is not directed horizontally but downward. Thearrangement can be made so, that the lamp carrier can be turned togetherwith the shade. Thereby the rays themselves of the lamp are directeddownward, or in any other direction, as desired.

As a second modification a shade coming from below is arranged besidethe shade coming from above, by which means it is possible to make theangle of the beam of light still smaller. This second shade can be madeof opaque material and eventually provided with perforations, or it canbe made of a translucent material, so that the luminous intensity can beregulated.

As a third modification a small folding table is connected to the lamp,which can be liapped downward, if the shade is turned before the lampthe beam of light falls directly on to the table. The table can beprovided with a writing-block, with a map, with a compass or the like.If desired this table can be connected to the shade, so that if thetable is liapped downward the shade is brought before the lamp, and isprevented from being turned back as long as the table is in the positionfor writing on it.

The accompanying drawings show four modifications of the electricpocket-lamp. Figure 1 is a side View ofthe first modification, partly insection, the shade being entirely o ened. Fig. 2 shows the same view,the sha e being partly set before the lamp and the lamp-carrier beingturned in the corresponding position. Fig. 3 shows a modification, inwhich a' second shade coming from below is provided. Figs. 4 and 5 showfront view and side elevation of a complete pocket-lamp with shade andtable.

According to the Figs. l and 2 the case (a) of the pocket-lamp isprovided with the two covers (ZJ) and (o). In the case (a) alamp-carrier (e) which has a holder for the glow-lamp (f) is pivotallymounted on pins (d). The lamp-carrier (e) contains a reflector and alens (g). Behind the lampcarrier a curved strip of metal (h) is arrangedto supply, the current to the glowlamp. Instead of the strip of metalalso a flexible wire canl be used to connect the glow-lamp to thebattery. The shade which consists of two shields (i) and (j) can beturned around the pins (d). The shield (j) slides over the shield (i)and if the shade is brought before the lamp irst the shield (j) will beturned around the pins (d). The shield (j) slides on the shield (i)until the catch (1) of the shield catches the iange (l) of the shield(i), whereby this shield turns also around the pins (al).

As shown in Fig. 2 it is possible to shade the light of the lamp so thatthe rays of light falling downward are limited to the angle (or) of Fig.2. At the same time the whole lamp-carrier turns around the pins (al) sothat the optical axis of the combination of reiector and lens comes alsoin an inclined position. Y

The modification according to Fig. 3 shows exactly the same arrangement,but another shade (m) is provided which comes from below and which canalso be turned around the pins (d).

By these two shades the light of the lamp can be limited to a narrowbeam of light. The lower shade (m) can be provided with perforations(j), to let pass some light if the shades are closed. The shade (m) canalso be made of a translucent material by whichl the light isconsiderably reduced.

According to the modification of the Figs. 4 and l5 the case (a) of thepocket-lamp is provided with a little table (n) which can be turnedaround the hinge (o). The table can be brought into the positionshown inFig. 5 in dotted lines. On the table a writing-block, a map, a compassor the like can b e fastened. The light' of the lamp falls directly onthe table (a) and illuminates it suiiciently.

If desired an interlocking device can be provided, which consists of abar which can be held in place by the guides g) of the case (a). The bar(p) has at its lower end a hook (r) against which a small lever (s)connected with the table (n) strikes. On the upper end the bar (p) isbent at (t) and strikes against the nose (u) of the shade (j) If thetable is apped downward the lever (s) strikes against the hook (r) ofthe bar (p) and displaces the bar (p) whereby the bar pushes the nose(u) of the shade by means of its bent end (t) so that at the same timethe light of the lamp is shaded and directed to the table. As long asthe table is lowered the shade cannot be opened. If the ytable isreturned to the position shown in Fig. 5 in full lines the bar (p) fallsdown and'now the shade can be opened.

Naturally any other connection can be provided between shade and table,for instance by rack and pinion or the like.

Now what I claim and desire to secure by Letters Patent is thefollowing:

1. In electric pocket lamps, the combination of a casing, pins extendingfrom the wall of said casing, a lamp carrier pivotally mounted on saidpins and screening means for the lamp pivotally mounted on said pinssubstantially as and for the purpose described.

2. In electric pocket lamps, the combination of a casing, pins extendingfrom the inner wall face of said casing, a carrier pivotally mounted onsaid pins, a lamp secured to said carrier, a stationary contact element'said casing, a table hinged to said casing and means connecting saidtable with said screening means whereby the said screening means areactuated by the movements of said table.

4. In electric pocket lamps the combination of a glow lamp, a pluralityof pivotally mounted shades for said lamp and a table hinged on the caseof the lamp and connected with the shades by a bar, substantially as andfor the purpose described.

5. In electric pocket lamps the combination of a glow lamp, a pluralityof pivotally mounted shades for said lamp and a table hinged on the caseof the lamp and connected with the shades by a bar, of which the upperend strikes against the nose of the shade while its under end touches alever of the table, substantially as and for the purpose described.

That I claim the yforegoing as my invention, I have signed my name, inpresence of two witnesses,x this 16th day of October, 1915.

JOSEF BECKMANN.
